METAL-POLISH.

Specification of Letters Patent.

Patented 0a. 11, 1910.

Application filed December 3, 1909. Serial No. 531,267.

T 0 all whom it may concern:

- Be it known that we, FREDERICK N. PEASE MILTON E. MCDONNELL, both citizens of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Metal-Polish; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to metal polishing compositions, and has for its object the productlon of a metal polish which will remain substantially uniform in composition under trying conditions.

With these and other ends in view the invention consists in the novel combinations of parts and their equivalents more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawing.

forming a part of this specification, the figure is a diagrammaticv view of a receptacle containing the polish. In carrying out this invention we preferably take 9 pints of paraffin oil, 9 pints of kerosene oil standing a test of'about 150, 1 pound of carnauba wax, 1 pound of stearic acid, 29 pounds of silex or other suitable finely divided abrading material, 3 fluid ounces of ammonia, and about 41 fluid ounces of amyl acetate or other perfuming agent.

The parafiin oil is preferably heated in any suitable vessel, when the wax and stearic acid may be melted in the hot paratfin oil thus produced, and the 150 kerosene can be then added. The silex or other. abrading material is now gradually stirred into the mixture, and when the temperature is at or about 150 F., the ammonia of about .90 specific gravity is added. If the temperature is much higherthan 150, a considerable portion of the ammonia will be lost, and if the temperature'is much below 150, the proper combination between the ammonia and the stearic acid will not occur. Scenting material.may be added at will, and any suitable perfume may be employed, but we have found amyl acetate very satisfactory.

When the mixture is at about 140 .or

150 in the pot it is of a consistency of a thick cream, and while in this condition may be poured into any suitable receptacle, such as the receptacle 1 shown in the drawings, and allowed to solidify when it becomes a semiviscous solid of a soft and smooth texture having a slight abrading sensation when crushed between the fingers.

Of course, it is obvious, that other mineral oils are interchangeable with those kerosenes disclosed, that equivalents of carnauba wax, such for example as ozocerite wax, may be substituted, and that the proportions may be widely varied without departing from the spirit of our invention. It is also evident that in some cases one or more of the constituents mentioned may be omitted,

. and that the order of mixing above set forth is not essential.

The carnauba wax presents a smooth and hard polishing medium, also a gelatinizing agent for the oils used; and since it is not gummy or tacky it leaves a clean, smooth surface. The ammonia combines with the stearic acid to form a "soap, or soap-like substance; and the silex acts as an abrader to mechanically remove any film or coating that may have been formed on the metal; while the mineral oils donot stick to the metal and constitute a ood vehicle for the other constituents, an also have some cleansing action. The polish when made is not corrosive to any appreciable extent and, therefore, if left in contact with the metal through accident or design will not injure or, discolor the same.

Whatwe claim is.

into the mass 2,

1. A metal polish comprising carnauba ammonia; a mineral oil; and an abrading material, substantially as described.

4. A metal olish comprisin carnauba wax; stearic 301d to which has be ammonia; a mineral oil; paraflin oil; and any abrading material, substantially as described;

5. A metal polish comprising carnauba wax one pound; stearic acid one pound; ammonia three fluid ounces; a mineral oil nine pints; paraffin oil nine pints; and twentych added monia three fluid ounces;

been added to the stearic acid atisubscan- 1o tially 150 F., substantially as described.

In testimony whereof, we aflix our signatures, in presence of two witnesses.
